在 zsh 上找不到 npm 全局安装命令

Question

我刚刚安装了包 live-server 使用 npm install -g live server

我检查了，该软件包当前安装在

/Users/username/.npm-global/lib/node_modules/live-server/live-server.js

但是，当我尝试从命令行运行 live-server 时出现错误

zsh: command not found: live-server

我需要做什么才能运行实时服务器？我安装了 oh-my-zsh，我担心这可能会导致我的问题。我知道这应该与设置我的 PATH 有关，但我不确定是什么。

运行 echo $PATH 会导致：

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/opt/ImageMagick/bin:/Users/username/npm-global/bin:/Users/username/npm-global/bin:/Users/username/npm-global/lib

以下是我的根目录中可能相关的一些文件。

谢谢

Answer 1

将export PATH=$PATH:/Users/username/.npm-global/bin 添加到 .zshrc 而不是 .bashrc 解决了我的问题

Answer 2

将此添加到我的 ~/.zshrc 为我修复了它

export PATH="$HOME/.npm-packages/bin:$PATH"

Answer 3

以这种方式设置以防止进一步的问题：

安装 NVM 来管理 Node 版本 使用 --lts 安装节点，以便获取最新版本 再次安装 NPM 最新版本

之后正确设置 .zshrc 文件。如果你使用 zshell，请不要使用 .bashrc，它有自己的配置文件，我想你已经更新了。

查看 NPM 页面 https://www.npmjs.com/package/live-server 尤其是这些部分：

Default options:
If a file ~/.live-server.json exists it will be loaded and used as default options for live-server on the command line. See "Usage from node" for option names.

Usage from node
var liveServer = require("live-server");
var params = ...
